PTERIDOPHYTA OF DOUBTFUL STATUS 
* POLYPODIUM ADIANTHOIDES Burm. f. FI. Ind. (1768) 234. “Habitat 
in Indiis.” 
Burman’s description was based on an actual specimen col- 
lected by Pryon, probably of Javan origin. The reference to 
Petiver Fil. 69 t. 2. f. 9, cannot be interpreted as the type of the 
species. The species is unrecognizable from the short descrip- 
tion alone, but it is probably no Polypodium. 
* POLYPODIUM GLABRUM Burm. f. FI. Ind. (1768) 235. “Habitat in 
Java, Zeylona.” 
The type is apparently a Javan specimen collected by Pryon ; 
Burman added a reference to Filix non ramosa, foliis integris 
non serratis, zeylanica minor Burm. Thes. Zeyl. (1737) 100, 
which is unrecognizable from the description and which may or 
may not represent the same species as the Javan fern. Burman’s 
species is unrecognizable from the description alone. 
* POLYPODIUM OVATUM Burm. f. FI. Ind. (1768) 233. “Habitat in 
Java.” 
The very brief description “fronde petiolata alterna, laciniis 
oblongis integerrimis” was based on a Javan specimen, but the 
identity of the species cannot be determined from the description 
alone. The species cannot be interpreted from the reference to 
Petiver Fil. 38, t. 14, /. 2, as this characterizes the variety /? of 
Burman’s species. 
* POLYPODIUM ROSTRATUM Burm. f. FI. Ind. (1768) 235. “Habitat in 
India.” 
This species was based on an actual specimen collected by 
Pryon with a reference to Plukenet Mant. 80, t. 399, f. 4. Bur- 
man compares it to Polypodium decussatum Linn., which is a 
Dryopteris. The species is unrecognizable from the description 
alone, but is evidently no Polypodium. 
* TRICHOMANES NIVEA Burm. f. FI. Ind. (1768) 237. “Habitat in 
utraque India.” 
There is little evidence that Burman had a specimen except 
in his statement “in utraque India.” It is probable that he 
had a specimen from India or Java. I have not seen Sloane’s 
figure which Burman cites as representing the species. The 
species is one of unknown status.
